Define global custom keybindings for shutdown.

This document (7021882) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12
SUSE Linux Enterprise Desktop 12

Situation

In forthcoming cases it may be required to create a custom shutdown keybinding globally.

In such a particular case, instead of for example displaying the shutdown prompt which by default shows when using 'Ctrl+Alt+Del', the system will than directly move to a 'Halt' state.

Resolution

1. Create a new user profile for dconf and add values into it

$ vi /etc/dconf/profile/user

user-db:user
system-db:local

2. Create a directory for the custom keyfiles

$ mkdir -p /etc/dconf/db/local.d

3. Create a custom keyfile, and add the following values

$ vi /etc/dconf/db/local.d/01-local-example

[org/gnome/settings-daemon/plugins/media-keys]
logout=''
custom-keybindings=['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/']
[org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0]
name='shutdown'
command='/sbin/shutdown -h now'
binding='<Control><Alt>Delete'

4. Save, and update, the dconf database :

$ dconf update

5. verify the changes in the dconf GUI :

$ dconf-editor

Cause

Additional Information

Explanation of the custom '/etc/dconf/db/local.d/01-local-example' file content :

   [org/gnome/settings-daemon/plugins/media-keys]
   (note **1 : specify the dconf schema path where the values )

   logout=''
   (note **2 : since 'Ctrl+Alt+Del' is used by default for logout, this needs to be changed to blank)

   custom-keybindings=['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/']
   (note **3 : creates a schema path for custom keybinding)

   [org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0]
   (note **4: custom keybinding schema path)

   name='shutdown'
   command='/sbin/shutdown -h now'
   (note **5: use the full path for any commands here)

   binding='<Control><Alt>Delete'
